The validity of Titmus Vision testing results

Area of Science:

• Optometry and Vision Science
• Ophthalmic Device Evaluation

Background:

• Standard optometric procedures are widely used for vision assessments.
• The Titmus Vision Tester is a screening device for various visual functions.

Purpose of the Study:

• To compare the diagnostic accuracy of the Titmus Vision Tester against conventional optometric methods.
• To determine if significant differences exist between Titmus Vision Tester results and open-field optometric procedures.

Main Methods:

• Visual acuities (near and distance) were measured using both Titmus and Snellen charts.
• Lateral and vertical phorias were assessed with Titmus and Maddox rod.
• Color discrimination was evaluated using Titmus and Ishihara plates.
• Stereo acuity was measured with Titmus and Stereofly Wirt Dot.

Main Results:

• The Titmus Vision Tester demonstrated comparable results to standard optometric tests for visual acuity.
• Phria measurements showed agreement between the Titmus Vision Tester and Maddox rod.
• Color discrimination and stereo acuity results were also consistent between the Titmus Vision Tester and respective standard tests.

Conclusions:

• The Titmus Vision Tester is a valid and reliable instrument for assessing key visual functions.
• Results suggest the Titmus Vision Tester can be effectively used as a screening tool in optometric practice.
